Lumia 810 charging shell/case

I just received my first Lumia 810 and I have exhausted myself looking for the wireless charging shells for the phone. I was under the impression there would be other colors beyond black and cyan. Any recommendations for a case that mimics a charging shell that's red or yellow? I really want one of those colors and I don't even have the wireless charging plate so it's an aesthetic move only.

I can't find any good cases for the phone on any retailer/carrier website. Totally frustrated. I don't want a boring black phone.
